Prehistoric Life During the Paleogene Period

Prehistoric Life During the Paleogene Period The 43 million years of the Paleogene period represent a crucial interval in the evolution of mammals, birds, and reptiles, which were free to occupy new ecological niches after the demise of the dinosaurs following the K/T Extinction Event. The Paleogene was the first period of the Cenozoic Era (65 million years ago to the present), followed by the Neogene period (23-2.6 million years ago), and is itself divided into three important epochs: the Paleocene (65-56 million years ago), the Eocene (56-34 million years ago) and the Oligocene (34-23 million years ago). Climate and Geography. With some significant hiccups, the Paleogene period witnessed a steady cooling of the earths climate from the hothouse conditions of the preceding Cretaceous period. Ice began to form at both the North and South poles and seasonal changes were more pronounced in the northern and southern hemispheres, which had a significant impact on plant and animal life. The northern supercontinent of Laurasia gradually broke apart into North America in the west and Eurasia in the east, while its southern counterpart Gondwana continued to fracture into South America, Africa, Australia, and Antarctica, all of which began drifting slowly to their present positions. Terrestrial Life Mammals. Mammals didnt suddenly appear on the scene at the start of the Paleogene period; in fact, the first primitive mammals originated in the Triassic period, 230 million years ago. In the absence of dinosaurs, though, mammals were free to radiate into a variety of open ecological niches. During the Paleocene and Eocene epochs, mammals still tended to be fairly small but had already started evolving along definite lines: the Paleogene is when you can find the earliest ancestors of whales, elephants, and odd- and even-toed ungulates (hoofed mammals). By the Oligocene epoch, at least some mammals had begun to grow to respectable sizes, though they werent nearly as impressive as their descendants of the ensuing Neogene period. Birds. During the early part of the Paleogene period, birds, and not mammals, were the dominant land animals on earth (which shouldnt be all that surprising, given that they had evolved from recently extinct dinosaurs). One early evolutionary trend was toward large, flightless, predatory birds like Gastornis, which superficially resembled meat-eating dinosaurs, as well as the meat-eating avians known as terror birds, but subsequent eons saw the appearance of more diverse flying species, which were similar in many respects to modern birds. Reptiles. Although dinosaurs, pterosaurs and marine reptiles had gone completely extinct by the start of the Paleogene period, the same wasnt true for their close cousins, the crocodiles, which not only managed to survive the K/T Extinction but actually flourished in its aftermath (while retaining the same basic body plan). The deepest roots of snake and turtle evolution can be located in the later Paleogene, and small, inoffensive lizards continued to scurry underfoot. Marine Life Not only the dinosaurs went extinct 65 million years ago; so did their vicious marine cousins, the mosasaurs, along with the last remaining plesiosaurs and pliosaurs. This sudden vacuum at the top of the marine food chain naturally spurred the evolution of sharks (which had already been around for hundreds of millions of years, though in smaller sizes). Mammals had yet to venture fully into the water, but the earliest, land-dwelling ancestors of whales prowled the Paleogene landscape, most notably in central Asia, and may have had semi-amphibious lifestyles. Plant Life Flowering plants, which had already made a cameo appearance toward the end of the Cretaceous period, continued to flourish during the Paleogene. The gradual cooling of the earths climate paved the way for vast deciduous forests, mostly on the northern continents, with jungles and rainforests increasingly restricted to equatorial regions. Toward the end of the Paleogene period, the first grasses appeared, which would have a significant impact on animal life during the ensuing Neogene period, spurring the evolution of both prehistoric horses and the saber-toothed cats that preyed on them.

Teacher Tenure in California Research Paper Example | Topics and Well Written Essays - 1250 words

Teacher Tenure in California - Research Paper Example he teachers become eligible for the tenure they gain security towards their position and can only be dismissed if the school authority is able to put forward a just cause. The state law even proposed that the tenured teachers may be dismissed if they are giving unsatisfactory performance (Jederberg 43). However, as per the policy if the performance of students is low in the state it is not considered to be a condition for dismissal of teachers which in turn has resulted into more number of students exhibiting low performance. The dismissal conditions as highlighted by the court decision states that the school authority needs to give a prior notice to the employee before initiating any form of proceedings regarding dismissal due to unsatisfactory performance of a teacher. The teacher tenure policy majorly focused towards the well being of students and to retain those teachers who performed well and discard those who are not able to meet the standards of the school policy. The ones who supported the policy stated that the policy majorly aimed towards development and growth of students so that they are able to perform well in their career path. The other end of this provision was that it provided the flexibility to the school authority to focus more on performing teachers and reduce the cost by eliminating those teachers who did not perform well. The notice that would be given to the teachers before the dismissal must also include some of the behavioral instances that need to be communicated three months prior to filing charges. The major purpose of the policy was not to hide the underperforming teachers behind the tenure and to facilitate more of academic achievement of the students. There are almost 6 million students who are enrolled in the public s chools of California and thus the law was to support these students so that they are provided with an appropriate guidance. The tenure is always a security provision for teachers but this policy was aligned more towards

A manner of analyzing globalization in historical standpoint has to do with the economic and social account of global affairs, and especially with the history of past stages of speedy boost in global trade, investment, communication, and authority. There have been more than a few such instances over the past centuries that come to mind. Among is the export and investment explosions of the 1860s and the earlier part of the twentieth century are merely a couple of the more remarkable instances. (2000) The history of these early periods, and of the institutions with which they were connected, is of substantial contemporary attention. Nonetheless, international history has to be far more than the history of the affairs involving states in the context of their international relations, or their conflicts, or their invasions and domains. It is in excess of the history of exports and imports among countries. (2002) It is over a comparative history. It have to be a history of affairs involving persons and customs, as well as people who belong to quite a lot of diverse cultures all together or who shift among diverse identities, modes of speech, home nations, and even nationalities. Characteristics of Globalization Globalization, has acquired considerable emotive force. Globalization has its own meaning from different individuals. For some, globalization is a process that is beneficial, i. e. a key to the future world economic development and also inevitable and irreversible. Others regard it with hospitality even fear, believing that it increases inequality within and between nations or organizations, threatens employment and living standards and thwarts social progress. Globalization (or globalisation) in its literal sense is a social change, an increase in connections among societies and their elements due to, among others, the explosive evolution of transport and communication technologies. The term is applied to many social, cultural, commercial and economic activities.

A Summary of the Communist Manifesto by Karl Marx Essay -- Communist M

A Summary of the Communist Manifesto by Karl Marx Karl Marx was an idealist. He observed the cruelties and injustices that the poor working class endured during the period of industrial revolution, and was inspired to write of a society in which no oppression existed for any class of people. Marx believed in a revolution that would end socialism and capitalism, and focus on communist principles. The Manifesto of the Communist Party, written by Karl Marx and edited by Frederick Engels, describes the goals of the communist party for ending exploitation of the working class and creating a society in which there is equality in society without social classes.1 The first part of the Manifesto is entitled the Bourgeois And Proletarians. Marx begins by explaining that the history of man and society is the history of class struggles. The modern bourgeois society has developed out of the feudal society, but in a simpler form: two classes opposing one another, the Bourgeoisie and Proletariat. With the discovery of America, and expanded markets across the world, the feudal system of industry no longer satisfied the increased needs of those markets. Manufacturing and modern industry soon took its place. This is how, according to Marx, the bourgeoisie increased their capital, advanced their political influence, and distinguished themselves from the working class. Marx accuses the bourgeoisie of turning respected professionals into wage-laborers. By creating large cities, they have centralized the population and means of production. This property then, is held by few, and so creates political power. The once independent towns and provinces are now brought together under one government with one set of laws. Despite the power that the... ...he struggles between the exploiting and the exploited. Marx concludes in the Communist Manifesto that a working-class revolution would overthrow the bourgeois and a classless society would exist.11 -------------------------------------------------------------------------------- 1.

Blue Collar vs. White Collar Work Essay

Throughout history the lives of the people in the working class have not always been easy. People always work hard to earn money and support their families; however, people don’t always work in a suitable working area. The term â€Å"Blue Collar† is jobs that require manual labor from people. The problem with these kinds of jobs is that the places the people work in can be extremely unsanitary and may cause a bad working environment for the people in it. Blue collar work is also the work most people do not want to do but it is needed for the people who do white collar jobs to prosper. Also blue collar workers are known as people who did not do well in school or people that aren’t smart. Well that is not the case with these workers because without them we wouldn’t be able to do some of the things we do now or be able to survive. Also some blue collar workers are called undocumented workers in which they don’t have any documents to prove that they can work or are from this country but help the country in doing jobs that are needed for a low wage. Therefore blue collar workers are a very important part to society and we need them to thrive. For example in â€Å"Made in L.A† there are 3 young Latina immigrants who work in Los Angeles sweatshops they do manual labor for an extremely low wage. Even though they did the same work as others they got paid less because they are immigrants, it is hard work with low wages but they continue to do it to support themselves and their family just like the blue collar workers do nowadays. With the little voice they had, they protested and tried to make a difference for all future immigrant workers not to be treated inferior to them. People in blue collar jobs get paid less than white collar workers which are office work but they enjoy their job other than others even though it is dirty. Even though the U.S has strict policies on immigrants, they are actually needed because they do many of the blue collar jobs that are needed in the country. For example in the article â€Å"Putting a S top to Slave Labor† it says that† If we required good documents starting tomorrow, the nation would plunge into an instantaneous economic crisis† (p156). This would happen due the fact that they do most of the jobs that people don’t want to do and get low wages also which are blue collar jobs. There are many instances of unsanitary work places. In the article â€Å"Migrant Farm Worker,† by Studs Terkel shows the conditions of the working place and also shows child labor. He says the animals were being treated better than the workers themselves. â€Å"Veterinarians tend to the needs of domestic animals but they can’t have medical care for the workers.†(p133) this shows that the bosses who supply these people with blue collar jobs are being taken advantage of and that the animals are living better than the workers. Also this goes to show what little care the bosses had for their people and that they only cared about the money instead of the needs of these people. People need to see the working class as people rather than machines that do something over and over again. Just because someone has to work hours in front of a machine and have a dirty job does not mean that the person is not a human being. There are many people needed in the world to do some jobs that which most people would not do. If we didn’t have those kind of people and if everyone wanted to do the same thing as everyone else than we would have a hard time surviving since it is needed to be done. â€Å"The case for working with your Hands,† states â€Å"More fundamentally, now as ever, somebody has to actually do things: fix our cars, unclog our toilets, and build our houses.†(18) This goes to show that if no one does those jobs there would be a lot of problems and that we always are going to need blue collar workers perhaps more than white collar in most cases. â€Å"The Case for Working with Your Hands,† also states â€Å"The trades suffer from low prestige and I believe this is based on a simple mistake. Because work is dirty, many people assume it is also stupid.†(19) The thing that people don’t realize is that not every job is going to appeal to them because we are all different and different people do different things, just as some people like to sit behind a computer everyday some people will not do that. The treatment of workers is a growing issue and it’s going to keep on growing and growing if people don’t realize what these big companies are doing and put a stop to it. For example the shoe company Nike employs many people but the thing people don’t know is that there are 12,000 young women in Indonesia making the lowest amount of money and working long tiring shifts. Every $80 sneaker Nike makes it only costs them 12 cents for the labor. This shows the unfair treatment of these workers and how the company is taking advantage of them and it is not only Nike doing this but any major company uses the same force of labor. In â€Å"Who Makes the Clothes We Wear?† it says â€Å"Government officials raided a sweatshop filled with immigrant Thai women laboring as little as 59 cents per hour.†Also not only were they being taken advantage of the discipline was enforced by threats of rape and beatings.(26) This goes to show the little care they have for these workers and the actions that are being taken against them. It also shows a dark side to these companies in which the workers are being treated worst than dogs. In the article â€Å"Reapers† by Jean Toomer it says that â€Å"Black horses drive a mower through the weeds and there, a field rat, startled, squealing bleeds, His belly close to ground. I see the blade, Blood-stained, continue cutting weeds and shade.† (37) This article shows tough field work for black people back around the 60s. They were bleeding but their determination was too great and they continued to go and do their work. Slavery could be identified as blue collar work also. In the article â€Å"What to the Slave is the Fourth of July?† Frederick Douglass says â€Å"There is not a man beneath the canopy of heaven who does not know that slavery is wrong for him.† (140)This shows that everyone knows that slavery is wrong but they continue to do it disregard the health of the workers but the financial health of a company or a person. Slaves have to endure much pain and long haggard days with little to no pay working out on the fields and any other job that another man won’t do. Just like the slaves do these kinds of work the women in Indonesia could be compared to them because of the long working hours and the little pay with strict discipline. There is a growing problem with Third World women and how they are being used. The companies get young girls and give them work usually being blue collar work with bad working conditions and poor pay. In the article â€Å"Life on the Global Assembly Line,† it says â€Å"Older† women, aged 23 or 24, are likely to be laid off and not rehired. The lucky ones find husbands. The unlucky ones find themselves at the margins of society-as bar girls, â€Å"hostesses,† or prostitutes.†(29) This displays the women as disposable workers; once they get too old they are thrown out and out of a job. After that these women don’t have anywhere to go, some get a husband and are being taken care of and others have to resort to whatever that is needed to be done to get by. Although the problems to these blue collar workers are plain to see, the fact is that the country needs them for the economy to thrive. Even if blue collar workers are needed to have a successful economy it doesn’t change the fact that they need to be treated like people and not like dogs on the street.

Xml And Java Essays - Markup Languages, Technical Communication

Xml And Java Essays - Markup Languages, Technical Communication Xml And Java XML and Java Abstract Most web developers are intimately familiar with HTML, which is a language for presenting information on-screen so that it can be read by a human. A new markup language is rapidly gaining attention, however. XML allows for the presentation of information which can be read by a computer program. It is likely that the future of web development includes the creation of increasing numbers of programs, which make intelligent use of the data on XML-based web pages. And Java is a very good language for creating those programs. There has been a close relationship between Java and XML since the earliest mention of XML. John Bosak of Sun Microsystems, Chair of the XML Working Group has said that XML gives Java something to do (Web Techniques, pg. 43). Since there has been a decision to provide a standard Java API for manipulating XML (WT Pg. 43), the use of Java to manipulate XML documents is likely to continue, and increase over time. What is XML? XML stands for eXtensible Markup Language. It looks a lot like HTML. In fact, both HTML and XML are commonly viewed as a subset of SGML (Standard Generalized Markup Language). SGML is very complicated, a fact that has lead to its failure to gain widespread usage. HTML, its greatly simplified descendant, has been a resounding success, but it is beginning to demonstrate some significant limitations. XML is in between these markup languages in terms of complexity. It is more complex than HTML, but still significantly less complex than SGML. (Dynamic Web Publishing Unleashed - Pg. 744-745). It is essentially an attempt to define a common ground between HTML and SGML. Like SGML, XML is a metalanguage for defining markup languages. XML allows you to define your own markup language consisting of new tags which you can use to encode the information in your web documents far more precisely than can be done with HTML. XML is not a replacement for HTML. It is, instead, a supplement to HTML. While HTML will continue to be used for standard web pages, XML will be useful for applications that need more intelligent documents and more processing ability (DWP - Pg. 745). The main limitations of HTML are lack of extensibility, structure, and validation. (http:// metalab.unc.edu/pub/sun-info/standards/xml/why/xmlapps.html). Extensibility. HTML has a fixed number of tags. While the W3C and browser developers can (and frequently do) add tags, users cannot create their own tags to more accurately describe their data. Structure. HTML does not support the creation of nested tags, which would be used to describe and represent databases or object hierarchies. Validation. HTML does not support document validation. It has no means of allowing an application to check the data for validity, or to ensure that the markup is correct and well formed. XML differs from HTML in all three of these major areas: It allows developers to define new tags and attributes as needed It allows document tags to be nested as deeply as needed. Any XML document can include or make reference to a description of its grammar and syntax for use by applications that need to validate the structure of a document. XML will be most widely used in applications, which cannot be accomplished within the limitations of HTML. According to Jon Bosak of Sun Microsystems (Future of the web) These applications can be divided into four broad categories: Applications that require the Web client to mediate between two or more heterogeneous databases Applications that require the Web client to present different views of the same data to different users. Applications that require the Web client to present different views of the same data to different users. Applications in which intelligent Web agents attempt to tailor information discovery to the needs of the individual users. One more quote from Mr. Bosak: XML can do for data what Java has done for programs, which is to make the data both platform-independent and vendor-independent. Why Java? It can be argued that Java is an ideal language to use to create the applications listed above. At the most obvious level, both have been promoted almost exclusively for use in Web environments. But several features of the Java language make

How to Estimate Standard Deviations (SD)

How to Estimate Standard Deviations (SD) The standard deviation and range are both measures of the spread of a data set. Each number tells us in its own way how spaced out the data are, as they are both a measure of variation.  Although there is not an explicit relationship between the range and standard deviation, there is a rule of thumb that can be useful to relate these two statistics.  This relationship is sometimes referred to as the range rule for standard deviation. The range rule tells us that the standard deviation of a sample is approximately equal to one-fourth of the range of the data. In other words s (Maximum – Minimum)/4. This is a very straightforward formula to use, and should only be used as a very rough estimate of the standard deviation. An Example To see an example of how the range rule works, we will look at the following example. Suppose we start with the data values of 12, 12, 14, 15, 16, 18, 18, 20, 20, 25. These values have a mean of 17 and a standard deviation of about 4.1. If instead we first calculate the range of our data as 25 – 12 13 and then divide this number by four we have our estimate of the standard deviation as 13/4 3.25. This number is relatively close to the true standard deviation and good for a rough estimate. Why Does It Work? It may seem like the range rule is a bit strange. Why does it work? Doesn’t it seem completely arbitrary to just divide the range by four? Why wouldn’t we divide by a different number? There is actually some mathematical justification going on behind the scenes. Recall the properties of the bell curve and the probabilities from a standard normal distribution. One feature has to do with the amount of data that falls within a certain number of standard deviations: Approximately 68% of the data is within one standard deviation (higher or lower) from the mean.Approximately 95% of the data is within two standard deviations (higher or lower) from the mean.Approximately 99% is within three standard deviations (higher or lower) from the mean. The number that we will use has to do with 95%. We can say that 95% from two standard deviations below the mean to two standard deviations above the mean, we have 95% of our data. Thus nearly all of our normal distribution would stretch out over a line segment that is a total of four standard deviations long. Not all data is normally distributed and bell curve shaped. But most data is well-behaved enough that going two standard deviations away from the mean captures nearly all of the data. We estimate and say that four standard deviations are approximately the size of the range, and so the range divided by four is a rough approximation of the standard deviation. Uses for the Range Rule The range rule is helpful in a number of settings. First, it is a very quick estimate of the standard deviation. The standard deviation requires us to first find the mean, then subtract this mean from each data point, square the differences, add these, divide by one less than the number of data points, then (finally) take the square root. On the other hand, the range rule only requires one subtraction and one division. Other places where the range rule is helpful is when we have incomplete information. Formulas such as that to determine sample size require three pieces of information: the desired margin of error, the level of confidence and the standard deviation of the population we are investigating. Many times it is impossible to know what the population standard deviation is. With the range rule, we can estimate this statistic, and then know how large we should make our sample.

Molesworth Manor Communication Campaign Coursework

Molesworth Manor Communication Campaign - Coursework Example As a result, it is vital that Molesworth Manor devise a way to avoid this occurrence since the profitability may be ultimately affected. It is for this reason that empty nesters have been targeted as the next market for Molesworth Manor. This is a group of lonely people since they have no school-going children unlike the ones that Molesworth Manor has been targeting. The current situation is that this group is not among the people targeted by Molesworth Manor. Yet, these people need not wait for their children to come on holiday to book for rooms at Molesworth Manor. Therefore, it is highly recommendable that this group be targeted this year. For this sole reason was this reported created to ensure that Molesworth Manor remains profitable irrespective of the period. Molesworth Manor (MM) has been actively engaged in the hospitality industry for several decades now where its brand has been tremendously celebrated. The geographic location of Molesworth manor favours it in various ways including having some of the wealthiest counties around. The towns of Hampshire, Buckinghamshire and Surrey are some of the towns named as the wealthiest with every household having at least one car. Further, this hotel’s location prides itself for having a great number of empty nesters. Additionally, the infrastructure is not a problem in the area meaning clients can access the hotel without any inconveniences at all. In light of the above, the objectives Molesworth Manor wishes to achieve in this campaign include finding a solution to the months when there is low occupancy. Normally, Molesworth Manor is mostly booked during the school holidays when the families spend several days there. However, the months of February, March and October are adversely affected since not many families book the hotel during this time.

Clinical evidence and presentation Essay Example | Topics and Well Written Essays - 1500 words

Clinical evidence and presentation - Essay Example Psoriasis is a long-term condition, often re-surfacing after years of remission. It is often treated depending on the severity of the disease and body surface covered. Topical solutions like creams, ointments, and lotions are usually preferred treatment methods for mild forms of the disease. For the more moderate to severe manifestations of the disease, pills, injections and light treatments are used, as topical solutions are insufficient to manage the disease. This paper will critically analyze the current clinical evidence to support the management of the disease, reviewing one mainstream over the counter therapy and one complementary/alternative therapy for the disease. This paper will review the drugs Daivonex, Exorex, and alternative medicine treatment options, and assess their effectiveness in treating psoriasis. Daivonex, a non-steroidal medication containing calcipotriol is currently one of the main drugs being used for the treatment of psoriasis. Some practitioners have reviewed this drug and found it ineffective and inapplicable for some types of psoriasis. Daivonex is not applicable for widespread (all over the body) psoriasis. For those who suffer from some types of psoriasis like guttate, generalized pustular psoriasis, or erythrodermis psoriasis, Daivonex is also not applicable (Medical-Look, 2008). In applying the medication, the patient has also to be cautioned about getting any of the medicine on unaffected skin, as it can cause skin irritation. Clinicians do admit that Daivonex is recommended safe for most psoriasis sufferers, but they caution that there are some potential users of the drug that need to consult with their doctors before using it. Allergy to calcipotriol and any drug containing such ingredient can trigger allergic reactions. Allergic reactions tend to include difficulty in breathing, wheezing, swelling of the throat, face, lips, or tongue, rashes or hives. There are various precautions which are required for
